ANTIFERROELECTRIC LIQUID CRYSTAL DEVICE

摘要

PROBLEM TO BE SOLVED: To provide an antiferroelectric liquid crystal device which can sufficiently decrease the luminance of black color and can realize display with high contrast. SOLUTION: An AC electric field of a high voltage at a low frequency not to decompose an antiferroelectric liquid crystal layer 15 is preliminarily applied for a specified time between a signal electrode 12a and a selective electrode 12b. The liquid crystal molecules respond and move by the spontaneous polarization induced by the AC field, and the movement of the molecules forms a bookshelf-like structure in the antiferroelectric liquid crystal layer 15. Thus, zigzag defects or parabolic focal conic defects in the antiferroelectric liquid crystal layer 15 are eliminated and a good alignment state can be obtained.
